Jacob L. ★★★★★

The intake duration of 249 degrees really woke up the midrange on my 08, and the 9.5mm lift specs were spot-on for the install. Set the tappets to 0.20mm as listed and it fired up clean, no drama.

Robert ★★★★★

Swapped these in and the exhaust lift of 8.7mm really wakes up the mid-range. The duration specs are spot-on for my track setup.

Eva U. ★★★★★

Installed these camshafts and the intake lift of 9.5mm really woke up the mid-range; paired with the recommended valve cotter set for peace of mind. My bike pulls noticeably harder now without losing any top-end smoothness.
